Abstract: PURPOSE:To decrease the transmission loss in the outermost peripheral part so that uniform image observation can be made by forming the clad of the outermost layer of an image circle to the thickness equal to or larger than the clad thickness in the central part. CONSTITUTION:A material having the refractive index approximately equal to the refractive index of the clad of a coated image fiber 23 is first deposited by evaporation in the inner peripheral surface of a jacket tube 22 of a base material 21 for the image fiber to form a deposited layer 24. Many pieces of the coated fibers 23 are packed into this jacket tube 22 to form the base material 21 for the fiber. This base material is drawn under heating and melting by the same method as heretofore to form a coating 27 on the jacket 28, by which the image fiber 20 is obtd. The clad thickness t3 of the outermost layer is, therefore, the sum of the thickness of the deposited layer 24 and the thickness of the clad 26 of the coated fibers 23 and is the same as the clad thickness t2 in the central part. The transmission loss in the outer peripheral part is decreased and the observation of the uniform images is possible.

Abstract: PURPOSE:To suppress the spread of a light source and to save space, to increase the utilization efficiency of illumination light, and to imprint a sharp image by using an optical element which has a concave incidence surface and a convex projection surface for a data carrier and projecting irradiation light. CONSTITUTION:A data imprinting device 1 consists of a base plate 10 fixed to a rear cover 3, a lamp 11 fixed to the base plate 10, a prism 12, a liquid- crystal plate 13, and a circuit unit 14. The prism 12 has the concave incidence surface S1 and convex projection surface S2, has negative refracting power on the whole, and projects the convergent illumination light of a lamp 11 from a surface S3. The negative refracting power of the surface S1 reduces the image of the filament of the lamp 11 viewed from the plate 13 to eliminate the need to leave a large gap between the plate 13 and lamp 11, and the positive refractive power of the surface S2 prevents the unnecessary spread of the illumination luminous flux; and the aspherical shapes of the surfaces S1 and S2 improve the illumination efficiency. Consequently, the space is saved and the blurring of an imprinted data image to make the image sharp.
